(Cl. 'l2-99) 7 Claims.

This invention relates to composite windows of a decorative or displaynature.

Many types of decorative or display windows and glass panels haveheretofore been proposed. One such type is the conventional leaded glasswindow which consists or" transparent or translucent pieces of glassheld together in a series of lead channels. Such a unit is usuallysupported in a wood or metal frame which is built into the associatedbuilding structure. This construction is expensive and employs asubstantial amount of metal. The lead channels projecting beyond theface of the glass tend to hold dirt and make cleaning a difficultoperation. Moreover, such an assembly is inefcient in the conservationof heat since the metal parts employed provide a good heat transfermedium.

An object of the present invention is to provide a composite windowhaving a smooth, continuous, easily maintained glass surface. Anotherobject is to provide such a window wherein the decorative or displayelement constitutes a thermal barrier. Still another object is top-rovide a window unit comprising a composite assembly of concrete,plastic composition, and glass, which may be easily installed in masonrywalls by artisans having ordinary skill, and which eliminates the use ofmetals and other difiicultly available construction materials.

IThe manner of attaining these and other ob jects will become apparentfrom the following description of the invention, with particularreference to the accompanying drawing, in which:

Figure l is a side elevation of a window constructed in accordance withthe invention,

Figure 2 is a sectional end elevation of the window,

Figure 3 is an enlarged sectional end elevation of a portion of thewindow,

Figure 4 is a side elevation of a slightly varied form of window, and

Figure 5 is an enlarged sectional, partial, end elevation of a modifiedform of window structure.

Referring to the drawing, the window shown comprises a pair ofsubstantially similar concrete frames l and 2, which may be readily castor molded in a simple trough mold. The inner or meeting faces 3 and ofthe frames are substantially identical. A decorative or display panel orpartition 5 of a suitable synthetic plastic composition, such aspolystyrene, is interposed between the frames l and 2. The panel 5 has acontinuous marginal portion 6 which extends throughout the area ofmeeting faces 3 and 4 and projects somewhat beyond the inner cornerportions of the frames to provide a flange or strip l for engagement bythe peripheral portions of a pair of glass sheets B, the main portion ofthe panel being sandwiched between such glass sheets. During assembly,the opposite side surfaces of the panel portion t are softened as by useof a suitable solvent and then pressed between the faces 3 and l to formon hardening a sealing lm 9 on each side of portion and bonding thelatter to the faces 3 and Il.

The edges of each glass sheet are seated in a glazing strip lll, whichmay comprise a molded rubber or like resilient strip or any suitableglazing compound of conventional nature, which will adequately seal theglass sheets in the assembly. Preferably, the inner corners of eachframe l and 2 are recessed at Il to receive the glazing strip, thelatter being wedged into the recess and thereby exerting sealingpressure on the edges of the glass sheet.

The outer corners of each frame l and 2 adjacent the periphery of panel5 are preferably recessed as indicated at l2 to receive a waterproofsealing compound or strip I3, which engages the peripheral edge of panel5.

The decorative or display motif incorporated in panel 5 may vary asdesired. As shown in Figures 1 and y2, it may comprise a plurality ofcut-out openings forming a series of transparent areas lll andtranslucent or opaque bars I5. As shown in Figure fl, it may compriseportions i@ of decorative outline which may be in connected ordisconnected relation to each other. Alternatively, as illustrated inFig. 5, the motif may be formed by pockets or depressions Il of varyingdepth and outline in the. plastic panel. The pockets il', normallyfilled with air, cause a refraction of light not possible Where theglass and panel are in intimate contact. The differences in refractionof the transmitted light proj vide a plurality of areas of contrastingshades, which enhances the appearance of the panel. Portions of thepanel may be formed in contrasting colors.

The concrete frames each has a generally rectangular section which iseasily formed and .readily disengaged from a rigid mold. As shown,

I3, and the outer periphery of the glass sheets 8 being in sealingengagement with the resilient glazing strips l0. The extension of thepanel for the purpose of providing the ledge 'l against which one sideof each glass sheet bears and the provision of the recesses Il toreceive the resilient glazing strips is advantageous.

The fact that the glass sheet on either side of the panel may be removedand replaced independently, greatly simplifies repairs and reduces costof maintenance. i

Ii desired, frame 2 may be recessed as indicated at i9 to receive a sill20 of a Window supporting structure 2|.

What is claimed is:

1. A composite window structure comprising a pair of separate masonryframes arranged in laterally alined relation, a plastic compositionpanel having a continuous marginal portion rigidly sandwiched betweensaid frames and supported thereby, said panel having a continuous ledgeportion projecting inwardly beyond said frames, a resilient glazingstrip seated on each of said frames in juxtaposed relation to said ledgeportion, and a pair of glass sheets, the edge oi each sheet being seatedin a respective one or" said strips and each having its peripheralportion engaging said ledge portion, said panel being thereby alsosandwiched between said glass sheets.

2. A composite window structure as defined in claim l., said panelhaving cut-out openings therein forming a display motif.

3. A composite window structure as defined in claim l, said panel havingin one surface thereof depressions forming a display motif.

A composite window structure as defined in claim 1, said panel having inone surface thereof depressions of varying outline and depth to form adisplay motif therein.

5. A composite Window structure comprising a pair of separate masonryframes arranged in laterally alined relation, said frames havingsubstantially identical faces in spaced, facing relation to each other,a plastic composition panel having a continuous marginal portion rigidlysandwiched between said meeting faces and supported thereby, said panelhaving a continuous ledge portion extending inwardly beyond the innercorners of said frames, a pair of glass sheets each having itsperipheral portion engaging said ledge portion, said panel being therebyalso sandwiched between said glass sheets, and a resilient glazing stripseated on each of said frames in juxtaposed relation to said ledgeportion, the edge of each glass sheet being seated on a respective oneof said strips.

6. A window structure as defined in claim 5 each said fraine having arecess therein extending continuously around the inner corner thereof,said glazing strip being seated in said recess.

'7. A window structure as defined in claim 5, each said frame having arecess therein extending continuously around an outer corner thereofadjacent the periphery of said panel, and a sealing strip seated in saidrecess and engaging the periphery of said panel.
